SANTA CRUZ — A 30-year-old Santa Cruz deputy harbormaster was arrested earlier this month on allegations that he punched a man outside a party in Napa County.

Another victim in the Aug. 13 fight was struck in head with a pitchfork and remained in a hospital on Tuesday.

The trouble started during Timothy James Anderson’s 30th birthday party at a home near Lake Berryessa, said Napa County sheriff’s Capt. Leroy Anderson. Just before 9:30 p.m., three neighbors came to the home to complain about noise.

Anderson — a Santa Cruz deputy harbormaster who started the job in April — confronted the neighbors with 30-year-old Steven Dylan Belmont of El Dorado County.

They argued with the neighbors. Belmont picked up a pitchfork and “swung it at one of the other neighbors, striking him on the left side of his head near the midline of his ear, rendering him unconscious,” deputies wrote in a statement.

Belmont then chased the others with a pitchfork and threatened to kill them, according to the Sheriff’s Office.

The man struck with the pitchfork suffered a skull fracture, authorities said.

Belmont was arrested on suspicion of attempted homicide, mayhem, making threats and assault with a deadly weapon, according to deputies. Timothy Anderson was arrested on suspicion of misdemeanor battery and booked into Napa County Jail. He posted $5,000 bail.

Tuesday, officials at the Santa Cruz Small Craft Harbor did not return calls about the case.
